Get your cell phone out and photograph each part before you remove. It will help you with the reassembly process.

You might also want to make sure your floor is well swept and that you get a large cardboard box. Cut out one side and the top. Line the bottom with something light color and tape it in place. Do all your work within the box. This way if parts compete with NASA and try to go orbital, you will recover them easier (less time on your hands and knees on the floor).
